SAFETY FIRST!
Your DEMCO E96 Polisher/Grinder is designed with your
safety in mind. However, as with all power equipment, an
adherence to standard precautionary safety procedures will
protect the operator from possible injury.
RULES FOR SAFE OPERATION
POWER SUPPLY
The Polisher/Grinder is equipped with a three-pronged electrical plug intended
for a grounded three-hole receptacle. If an adapter is used to accommodate a
two-pronged receptacle, the adapter wire must be attached to a known ground.
EYE PROTECTION
Always wear safety glasses or an eye shield while operating the grinder. As
with any power tool, there is always a possibility of foreign objects being
thrown into the eye.
FUSE REPLACEMENT & BOTTOM COVER PLATE REMOVAL
(All Models)
Unplug the electric cord before attempting any service with the bottom cover
plate removed.
BELT GUARD
The belt guard must be in place while the polisher/grinder is in operation.
WEAR PROPER APPAREL
Do not wear loose clothing, jewelry, ties, ribbons, etc. See warning on back.
TURN GRINDER “OFF” AFTER COMPLETION OF WORK
OPERATION & MAINTENANCE
SPINDLE OPERATION
The collet is the part of the spindle nose with jaws that grasps a mandrel. To open the collet,
move the lever in (Figure 1) to the extreme left. Insert mandrel into the collet and move the lever
to the right.
Caution: Never c ose co et without having a mandre or simi ar too inserted. Spind e wi bind
if ever is in position “A” without a mandre in the co et.
To stop the mandrel, apply the brake by positioning the lever to the left. Once the mandrel stops,
stones and points can be removed and replaced in the collet. DO NOT app y the brake too
quick y, since mandre s may unscrew, causing need ess wear. By loosening the set screw,
(Figure 2) the handle may be adjusted to the most comfortable operating position.
COLLET ADJUSTMENT
Please visit our website for techni ue videos on proper
care and usage.
If mandrel is loose when in the operating position, adjustment
of the collet may be necessary.
1) Open the collet to position.
2) emove collet wrench from the end of the lever.
3) Place collet wrench in the collet and turn counter clockwise
to remove the collet.
4) Insert the hex wrench through the spindle nose and engage
the set screw deep inside the spindle.
5) Turn hex wrench clockwise to tighten (or counter-clockwise
to loosen).
6) einstall the collet using the collet wrench..
Not : If this procedure does not tighten the collet, replacement
of the collet may be necessary.
SPINDLE FAILURE
Caution: Spind e wi not run without a too or mandre inserted in the co et.
A ways check the co et first!
1) The collet must be clean.
2) Make sure the collet is not rusty and that it is lightly lubricated.
3) The collet must be screwed all the way in, with the clutch lever in position “C”.
4) Check to see if the collet is worn out. If it is, replace it.
5) If the spindle binds, it is usually the fault of the collet (it is advisab e to have a new co et
on hand at a times).
Should the spindle become noisy or otherwise faulty, we can repair it for a fee.
SPINDLE CLEANING
Periodically, remove the collet (see COLLET ADJUSTMENT) and clean it. Also clean the
inside of the spindle nose to remove debris. Do not oil the spindle or collet.
